Outputs

Each DVE board supplies three signals to the Combiner board: video, key, and
graphics. The video signal is either a transformed version of the A input
(Video+Key or Video-Key+Shadow modes) or of the combined A and B inputs
(Video/Video mode). The key signal is either a transformed version of the B
input (Video+Key or Video-Key+Shadow modes) or an internally generated
raster-shaped edge key (Video+Video mode). The graphics signal has a channel
identifier and up to three axis cursors per channel, which are visual clues used
for creating complex objects or movement.

The video and key signals connect to both the DVE Combiner and the Target
Framestore keyers. The DVE Combiner combines the two DVE boards' com-
bined video and key signals into a single composite of the four channels. This
combined output is then keyed over the optional Target Framestore (TFS) and
the background.
